Change the default subscription type when using Business Units.
Running business units in HubSpot, we're unable to change the default subscription type when giving a one-time legal basis for sending an email. In order for contacts to receive one-to-one emails, they have to be subscribed to the default one-to-one email subscription.
This is not helpful since we created new subscription types across each business unit to opt-in with contacts with the emails they want to receive.
Please consider adding sales email functionality with business units.
